David Smiley commented on SOLR-4586:
------------------------------------
bq. For Lucene, choosing TermsFilter is probably a viable solution much of the
time, but this issue is for Solr. It's linked to a similar issue for Lucene. My
Lucene knowledge is very pitiful, I know enough to be dangerous but not useful.
In my head, I imagine that reworking Solr to eliminate/reduce the use of
BooleanQuery is a monumental task. Am I right about that?
The solr user would be un-impacted because they very well may choose to ignore
the warning. If they have some basic Lucene knowledge, they could write a
QParser that builds a ConstantScoreQuery from a TermsFilter. It's a piece of
cake and if I wasn't so darned busy I'd do it myself because it's something
Solr should have.

> In the #solr IRC channel, I mentioned the maxBooleanClauses limitation to
> someone asking a question about queries. Mark Miller told me that
> maxBooleanClauses no longer applies, that the limitation was removed from
> Lucene sometime in the 3.x series. The config still shows up in the example
> even in the just-released 4.2.
> Checking through the source code, I found that the config option is parsed
> and the value stored in objects, but does not actually seem to be used by
> anything. I removed every trace of it that I could find, and all tests still
> pass.
